After working six years as a senior executive for a multinational payroll-processing company in Barcelona, Spain, Mr. Vildosola is cutting his professional and financial ties with his troubled homeland. He has moved his family to a village near Cambridge, England, where he will take the reins at a small software company, and he has transferred his savings from Spanish banks to British banks.

“The macro situation in Spain is getting worse and worse,” Mr. Vildosola, 38, said last week just hours before boarding a plane to London with his wife and two small children. “There is just too much risk. Spain is going to be next after Greece, and I just don’t want to end up holding devalued pesetas.”

Mr. Vildosola is among many who worry that Spain’s economic tailspin could eventually force the country’s withdrawal from the euro and a return to its former currency, the peseta. That dire outcome is still considered a long shot, even if Spain might eventually require a Greek-style bailout. But there is no doubt that many of those in a position to do so are taking their money — and in some cases themselves — out of Spain.
